* This routine can be used to generate new public key and private key
* pair. The `pkcs_name' is the name of public key algorithm, or if
* NULL it defaults to "rsa". The `key_len_bits' is the key length
- * in bits and if zero (0) it defaults to 2048 bits. The `pub_filename'
+ * in bits and if zero (0) it defaults to 4096 bits. The `pub_filename'
* and `prv_filename' is the public key and private key filenames.
* The `pub_identifier' is the public key identifier (for example:
* "UN=foobar, HN=hostname"), or if NULL the routine generates it
